There's a saying that suits well, the Hive City is like a swamp of filth, on the surface it seems calm, but once you step into it, all sorts of demons and monsters emerge.
Just like now.
Duanmu Huai decisively abandoned the idea of suppressing the riot first, and instead began a massacre in the Nest District. Obviously, Mutants and Chaos Believers were a huge threat, but when the Hive Mind descended from the sky, it was a completely different matter. Duanmu Huai would rather have a solo fight with a Great Demon than swim through the swarm of insects. After all, the former wasn't much of an effort to deal with, but the latter was an entirely different story. He had no interest in Human Sea Tactics.
Not to mention that this time his target was the Chaos Evil God, and he didn't want to waste time entangling with the Hive Mind.
However, the Gene Stealers here were equally troublesome.
